The basic functional unit(s) of compact bone tissue is/are _____________.
A
alveoli
B
nephrons
C
sarcomeres
D
osteons
Verified step by step guidance1
Understand the structure of compact bone tissue: Compact bone is dense and forms the outer layer of bones. It is organized into repeating structural units called osteons, also known as Haversian systems.
Learn the components of an osteon: Each osteon consists of concentric rings of calcified matrix called lamellae, which surround a central canal (Haversian canal) containing blood vessels and nerves.
Differentiate osteons from other anatomical units: Alveoli are air sacs in the lungs, nephrons are the functional units of the kidney, and sarcomeres are the contractile units of muscle tissue. None of these are related to bone tissue.
Recognize the role of osteons: Osteons provide strength and support to compact bone, allowing it to withstand mechanical stress and protect internal structures.
Conclude that the correct answer is osteons, as they are the basic functional units of compact bone tissue.
